Local Heat Transfer Distribution and Effect of Instabilities During Flow Boiling in a Silicon Microchannel Heat Sink [PDF]

, 2011
Flow boiling of the perfluorinated dielectric fluid FC-77 in a silicon microchannel heat sink is investigated. The heat sink contains 60 parallel microchannels each of 100 lm width and 389 lm depth.

Integration Strategy of Industrial Heat Pumps for Papermaking Process for Waste Heat Recovery Based on Factory Energy Management System

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Steam production in paper manufacturing still relies heavily on fossil‐fuel boilers, despite the presence of substantial recoverable low‐grade heat discharged through exhaust air and residual steam. To address this inefficiency, this study proposes an integrated steam‐generation heat pump (SGHP) and mechanical vapor recompression (MVR) system ...

Visualisation of subcooled pool boiling in nanofluids

Fusion Engineering and Design, 2019
Abstract High-performance cooling is of vital importance for the cutting-edge technology of today, from micro-electronic devices to nuclear reactors. Boiling heat transfer is expected to play a critical role for the safe and efficient operation of components exposed to high heat flux in future nuclear fusion reactors.

A Vapour Compression–Chemisorption System for Refrigeration and Cold Energy Storage in Warehouse Application

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Due to global warming caused by greenhouse gas emissions, cooling demand increases steadily globally. This rapidly increases the power demand for cooling from the electricity grid. Cold thermal energy storage (CTES) could shift the peak demand of cooling systems and thus ease the pressure on the grid.

Experimental Evaluation of an Enhanced Latent Heat Storage System for Domestic Hot Water Applications With Environmental and Economic Assessment

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Latent heat storage (LHS) systems offer high energy density and stable operating temperatures, making them suitable for domestic hot water (DHW) and residential heating applications. This study presents a pilot‐scale thermal energy storage (TES) unit with a nominal capacity of 7.5 kWh, employing a modified salt hydrate phase change material (PCM) and ...

Modeling and Optimization of the Immersion Evaporative Cooling Lithium‐Ion Battery System

Modelling and Simulation in Engineering, Volume 2026, Issue 1, 2026.
This paper focuses on the coupling mechanism, performance, and optimization of the immersion evaporative cooling lithium‐ion battery system (IECLBS). A novel dynamic coupling model is established based on the whole heat transfer path. We investigated the coupling mechanism of IECLBS by examining changes in the relevant parameters.

An experimental investigation of void fraction characteristics of flow boiling in a 5×5 rod bundle channel

Case Studies in Thermal Engineering
Flow boiling in the rod bundle channel is an important phenomenon in nuclear reactors. The local inhomogeneous void fraction distribution in the flow channel will affect the flow and heat transfer in two phase flow.

Thermal‐Hydraulic Sizing and Correlation Uncertainty Assessment of Printed Circuit Heat Exchangers as Steam Generators for Small Modular Reactors

Science and Technology of Nuclear Installations, Volume 2026, Issue 1, 2026.
Printed circuit heat exchangers (PCHEs) are strong candidates for once‐through steam generators in small modular reactors (SMRs), but their sizing is governed by coupled uncertainties in boiling heat transfer, dryout, and two‐phase hydraulic losses. This study examines a PCHE‐type steam generator in which the secondary side enters as subcooled water ...
